This is OK if you only use the virtual terminals. If you have any
VDUs directly connected through serial ports, it will not. In some cases
(Wyse VDUs for example) receiving unrecognised control characters can
hang the VDU, so that you have to do a power cycle of the VDU to recover it.
If you want to do this and also have VDUs, use the -i option to agetty
in the inittab file for the VDU connections; this will stop agetty from
displaying /etc/issue on VDUs that won't recognise the screen control

Come to me, all you who labour and are heavily laden, and I will
give you rest. Take my yoke upon you, and learn from me; for I am
meek and lowly in heart, and you shall find rest for your souls.
For my yoke is easy and my burden is light. (Matthew 11: 28-30)
